NQN-SKIDDING ATTACHMENT FOR WHEEL-TIRES.

Specification of Letters Patent.

Application led December 9, 1910. Serial No. 596,521.

To all Iwlw/u it m/fj/ cof/mem Be it known that I, GEORGE ALBERT LYON, a citizen ot the United States, residing in ll'iiladelphia, Pennsylvania, have invented certain improvements in Non-Skidding Attachments for theel-Tires, of which the following is a specification.

My present invention consists of certain modifications or' or improvements in the attachment for wheel tires for which I ,have liled applications for Letters latent on the and on the twenty-titth day of October, 1909, Serial' No. 525,283, the objects of my invention being to so construct the attachment as to insure relative rigidity of the sections when they are connected together, so that there will be no movement ot' the sections in respect to one another and consequent Wear at the points of connection; to simplify and elieapen the construction of the attachment; to'reduce to a minimum the number of parts comprisingthe same, andto permit adjustment ot the attachment to adapt it to varying ldiameters of tires. These objects l attain in the manner herinater set forth, reference being` had to the accompanying drawings, in which. -f

Figure l is a face view of the wheel having my attachment applied thereto; 1F ig. is a top or plan view of the wheel with the j attachment thereon, partof the wheel being broken away to show the connection between two sections of the attachment; Fig. 3 is a perspective view of one of the sections of the attachment Figs. land 5 are sectional views illustrating the; means for and manner of tightening the sections upon the tire and securing togetherl the overlapping `sections ot' the attachment, and Fig. 6 is a. face view of a wheel, drawn on asmaller scale, than Fig. l, and illustrating a means for rigidly` connecting the sections together to form a complete rigid attachment when the latter is composed of more than three sections.

ln F l and Q, l represents the telly of the wheel, usually of Wood, this telly however, being provided, by preference, with an external metallic ring which projects on each side ot the telly so as to form an annular yfiange- 2. Upon this ring is mounted in any ordinary manner the rubber tire 3 of the wheel to which my improved attachment is applied.

The attachment is composed ot similarv sections, preferably three in number, for a of June, 1909, Serial No. 499,199,

purpose hereinafter set forth. Fach sectie of the attachment composed of a flat :ip of bar Steel of appropriate dimensions, and of oblong cross section with rounded corners, each of these strips being bent se as io of tread members il, resting form a plurality f iat upon the surface of the tire and extendmg across the same from side to side. Ain

-intermedial side member 5 forms a rigid continuation of the tread members 4 oit the same section. Said intermedial side members 5 of the several sections are located on the inner side of the Wheel. The tread members 4 are also provided with side members G, located upon the outer side of the wheel. Said side members 6 of the tread members 4rof the same section are bent so as to project in' opposite directions, one forwardly and one rearwardly from the tread members of the sections. The side members G of one section ot the attachment overlap the members 6 of the adjoining section, as shown in Fig. l, and these overlapping side members are connected together preferably in such a way as will provide for adjustment ot' one in respect to the other in order to tighten the attachment upon the tire or to take up the attachment to compensate tor wear or' the tire, or to adapt one attachimfnt ttor use in connectionwith tires o' ditlierent diameters. In the present instance the overlapping side members 6 or' e'ljoiii sections of the attachment are s un i getherby pa, inga bolt 7 through registered openings in said ,i

overlapping side members, the bolts being retained in position by providing the same at one `end with a suitable head or enlargement and by providing the stem of the bolt with a slot for the reception of a suitable Cotter pin or key 9, the head of the bolt bearing upon the outer face of the overlapping side member 6 and the cotter pin or key bearing upon the inner face of the underlappimiside member G, as shown in'Fig. Q.. A

The bolt, however, may be reversed it desiredlnY order to draw the sections of the at- `tachment together and tighten the same upon the tire prior to the application of the retaining bolt 7` I use a bent lever l0, as shown .in Figs. 4 and the end portion et 'this lever being applied to an opening m the underlapping side member G, while the stem of the lever occupies an oj'iening in the overlapping member beyond that to which the inner end of the lever is applied, the bent lupon tlievside members 6 at one of the three portion of the lever lying between the two members, as shown in Fig. 4L. By moving the lever in the direction of the arrow, Fig. 4, the overlying and underlying members 6 oit the adjoining sections of the attachment are caused to 'move past one another, this movement continuing until the desiredopen ings of the two side members 6, other than those to which the lever 10 is applied, are brought into registry with one another, as shown in 'F ig. 5, whereupon the retaining bolt i' is inserted into such registeredopen- 'ings and the sections of the attachment are thereby retained in proper position, the le-v i ver 10 being free to be withdrawn from the openings to which it was originally applied. It is only necessary to act in this manner pointsv where said side members overlap each other, the overlapping ii'iembers at the other two points having previously been connected together by meanso the bolts and the operation o't' tightening the attachment upon the tire may, if desired, be assisted by pounding' or hammering upon the tread niembersof the attachment during the time Atliit the side members 6 are being drawn together by the action of the lever l0. One end of the lover l0 is preferably flattened or tapered as 'shown in Fig. 5, so that it may act as a screw driver or as a wedge for spreading thesplit cotter key 9 after the same has been passed through the slot in the retaining bolt 7.

By the use of but three sections in the attachment, the three points of connection s between said sections occupy the apices of rigid structure.

The intermedial side members 5 on one side oi' the Wheel and the 'overlapping side members 6, on the opposite side of the wheel,

present their longer axes in a radial line.l

The said iiiterniedial side member 5 rigidly holds the tread members 4, between which it foi-ins a continuation, in a position with their longer axes at right angles to a radial line and prevents the tread members of the saine section from rocking upon the tire and` by reason-ot the rigid construction of Y the complete attachment, Iy prevent any .fj movement between the'sections and thereby Joining` sections and forming a complete prevent the tread members of adjoining sections from having any lateral tvistiiig movement which would cause 'them to rock and bite into the material of which the tire is composed. `The interinedial side members `5 and the overlapping side members 6 being arranged as above stated with their longer axes in arradial line, said parts will present their broader surfaces parallel with the sides of the wheel and the tension upon the intermedial side members 5 and the side members G when the sections are connected under tension, will cause them to bend slightly upon-*their broader surfaces, as shown by ldotted lines in slightly, ya ,an angle; to the axisof the Wheel. This al/s'opoccurs when one tread member is in Contact with the ground and power is applied/to rotate the wheel. The tread :members other than the one in Contact with the ground will then assume av slightly diagonali'position acrossfthe tread of the wheel and fftlie side members will bear tightly agaiiis'tfthe's'ides of the wheel. of thel sidemembersr upon their broader surfaces is very slight and only occurs when the sectionsI are under tension, as all of the parts are of siiiiicient dimensions to insure the relative .rigidity of 4the ture forming the attachment. The connectionsbetween the sections are allen the outside of the wheel and are consequently lreadily7 accessible and the side members forming the 'points of connection 100 lextend sufficiently beyond the telly toward the center of the wheel to allow the connecting pins to be readily made fast. The' ,intermedi-abside members 5 of each section lare on the inside of the wheel and do not project toward the center of the wheel as fares the outergside members, thus giving more room for the driving mechanism upon the wheel. The intermedial side members 5 present their flat surface to the side of the 110 wheel and thus 'project but a very short distance from-the-same and will not interfere with the driving-sprocket chain usually located .close to the inside of the wheel.

` Owing yto the fewness of parts comprising and to the simpicmy improved attachment ity of coiistructioiiot each of these parts; the cost of the attachment is reduced and the application ,of the attachment to the tire and the tightening so simpliedthat itv can be :effected quickly and ,without trouble or the exercise of skill by the person applying the attachment.

I claim:

1. A non-skiddingwheel tire attachment 125 comprising la plurality or' sections, each sec- `tionhavinga 'plurality of tread members and aside meinbenrigidly connecting. the

same onjo'iie. side ofthe wheel, yand means disposeduon` the opposite side of' the wheel 1.30"-

Fig. 2, and the 80 tread me bers may assume a position The bending 90 complete struc- "y 95 of the same on the tire is E for directly but d etachably connecting said sections together to form a relatively rigid attachment.

2. A non-skidding attachment for Wheel tires comprising three sections, each presenting a plurality of tread members rigidly` disposed in relation to each other, and means at one side of the Wheel and oppositely projecting side members at the other side of the Wheel, and means for attaching the said side members of adjoining sections together, said points of connection bearing the relation to each other of the apices of an equilateral triangle whereby rigidity of the at tachment is insured.

4. A non-skidding attachment for Wheeltires comprising sections, each presenting a plurality et tread members of oblong cross section, intermedial side members forming a, relatively rigid continuation of said tread members on one side of the wheel, and side members oppositely projecting from the tread members on the other Side of the Wheel, the side members at the ends of adjoining sections overlapping and being secured together to form relatively rigid continuations of the tread members, and said overlapping side members and said intermedial sidewmembers being of oblong cross section and presenting their longer axes in a radial line whereby they can bend upon their broader surfaces When applied to the Wheel under tension.

5. A non-skidding attachment for Wheel tires comprising side members and tread members, the side members on the inner side of the Wheel being farther from the center of the Wheel than the outer side members.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
